Nautical Term: Draft, marks

Definition of Draft, marks

The ‘draft, marks’ are numerical values placed in a vertical scale at the bow and stern of a vessel. These marks indicate the draft, or the depth of water a vessel needs to float, at each point.

For example, a captain might consult the draft, marks on their vessel before entering a new harbor. If the marks indicate that the vessel needs a greater depth of water than what’s available in the harbor, the captain may need to consider an alternate destination.
